Tools Required: Towels or rags, compressed air, multimeter.
Remove any covers obstructing access to electrical connectors.
Use towels to dry off visible moisture on connectors and components.
Utilize compressed air to blow out moisture trapped in connectors.
Check for any signs of corrosion; clean any corrosion with a wire brush or contact cleaner.

3. Test and Replace Components (if necessary)

Tools Required: Multimeter, socket set.
Test the battery voltage. If below 12.4 volts, recharge or replace the battery.
Check the fuel pump relay and fuses using a multimeter; replace any faulty components.
If the fuel pump is not operational, replace it following the manufacturer's specifications.
Inspect and replace any damaged ignition components (e.g., spark plugs, ignition coils).
